A volume group is a filesystem that can be put onto a partition of a hard drive. What this filesystem type allows you to do is to break down that partition into smaller partitions (each one known as a logical volume), allowing for more compact & versatile storage management.

When trying to check or recover a logical volume it can be unintuitive to mount as you don't mount the /dev/sd**xY** partition, instead, the volume group on the partition needs activating and then the separate volumes can be mounted.

How To Link to heading

  • Identify the ID of the disk to be mounted:
[stuart@asuka ~]$ sudo fdisk -l
  • Display all volume groups:
[stuart@asuka ~]$ sudo pvs
  • Identify logical volumes for volume group:
[stuart@asuka ~]$ sudo lvdisplay /dev/VolGroup**XX**
  • Activate volume group:
[stuart@asuka ~]$ sudo vgchange VolGroup**XX** -a y 4
  • Mount the logical volume:
[stuart@asuka ~]$ sudo mount /dev/VolGroup**XX**/LogVol**XX** /mnt/
